GRANTCHESTER season 4 is coming back on screens tonight for its highly-anticipated new series. Here’s how to watch the James Norton detective drama online.

The long-awaited fourth season of Grantchester is almost here as fans eagerly await the return of the crime-solving clergymen to ITV. Robson Green and James Norton are joined by cast member Tom Brittney for the latest outing. Here’s how to watch the new series online.

The synopsis for season four reads: “It’s 1956 and with Amanda (played by Morven Christie) long gone, Sidney’s life now revolves around the church services and the interminable meetings of the Parochial Council and their plans for a village fete.

“He yearns for some excitement, and Geordie has noticed that Sidney’s devil-may-care attitude feels increasingly like a death wish.”

Series writer Daisy Coulam said that the theme of season four is “change”.

“Each series we look for a theme - the scars of the past, punishment and restitution, love versus duty,” she explained.

“This series, change itself was our theme: the evolution of our country and with it our characters.

“Series four was always going to be about change - in part because we had to say a sad good-bye to James Norton.
